The lamp and reflector 46, together with The block 35 is concaved at opposite edges to engage and bear against the battery cells 36, 37, as shown in Fig. 3, and the end portions of 20 are outwardly concaved to receive said cells; and the flaps 26, 27 of the exterior are adapted to lie covering, being flexible, against the rear surfaces of said cells, shown in Fig. 3, and retain the same in position between maincasing.

The conducting strip 43 secured within thegroove 420i the block 35 is in electrical connection at'its lower end with contact49, which is a'stri'p of metal extending from the conductor 43 and below the block 35 and then normally 'flexed upwa-rdly,

upwardly, as shown in Fig. 5, so as to make a firm electrical contact with the carbon or positive pole of the battery cell 37, asshown in Fig. 4, and the str'p is' electrically 1 continuous upwardly along the front of the block 35, with the strip 39, and the upper end of which is in engagement with the base-flange of, the threaded sleeve 38, an electrical connection between the positive pole of the battery'cell 37, sleeve 38, sleeve 48, reflector 46 andthe side of the lamp 45 being thus efi'ected, and since the strip 43, through the spring contact 49, is in engagement' with the negative POlQ of the battery 36, an electrical connection between said pole of said battery and the end terminal of the lampis formed. To complete there must be a connection between the negative pole of the battery 37 and positive pole of the battery 36, and to accomplish this-result I provide at the inner side of the top 23 of the easing two conducting strips 51 52 and a cir--' cuit making switch or slide 53, the latter being within a housing 54 secured to the top 23 of the casing-20 by suitable eyelets,

one of which, 55, is in electrical connection with the strip 51. The circuitmakingand breaking switch 53 is of customary type and it is in electrical connection with the hous-I ing 54 and maybe slid into electrical connection with an eyelet 56 (Fig. 7) securis in the position shown in the body 21 of the casing t let 56 will break the circuit and extingu the top and bottom of the a spring as shown in Fig. 5, so as to make a firm electrical engagement with the'zinc spreading 1 position. The flexing cells vertically,

, but when t 1e light has not been lighte Strip 52 to the switch 53'is moved to engage the eyelet 56,

thecircuit-will be completed and the lamplighted, the circuit then being from the switch 53 throughthe housing 54, eyelet 55, and strip 51 to the positive pole of the p attery cell 36, thence through said cell and the contact 49 and conductor 43 to one terminal of the lamp, and through the lamp, reflector 46, sleeve 38 and, conductors 39, 5.0 tothe positive pole of the battery 37,

and thence through the cell 37, contact strip 52 and eyelet 56 130 the switch 53. The sliding of the switch 53 from the eye- The circuit is. illustrated diathere are other known'forms of make-andbreak switches which may be substituted for the switch 53 and used to complete or break the circuit through the lamp and batteries.

At the back of the block 35 and preferably seated in part within the groove 42, is. a vertical strip 57, shown in Figs. 3, v4 and 6, whose upper and lower ends are bent rearwardly and secured to the topand bottom sections 23,' 24 of the casing. The strip 57 by closing the outervertical fside' of the-groove 42 excludes dust and dirt ish which might find its way into the interior of the block 35 and in additionserves to tie the top and bottom sections 23, 24 of the casing together, thereby stiii'eningthe casing and preventing said sections from outwardly from each other. When the strip 57 is made use of, reasonably thin material may be employed for the top and bottom sections of the main ca ing. I preferably form the upper and lower ends of the strip 57 with hooks or flanges which extend toward each other and serve, when desired, to receive a sheet of fiber or other suitable material 58, as 1 illustrate in Fig. 6 and also in Fig; 3, and which sheet of fiber will coiiperate with'the fiaps'26z, 27 in binding the battery cells in veryfirm of the spring conductors 49, 50 aids in binding the battery and when the construction as a whole has been completed we have a very compact and eflicient portable electric light.

in Figs. 1 to 8 incluswe l illustrate the 37 as reversed end for end, the

positive pole of the cell 36 being uppermost 9 and the positive pole of the cell 37 extended downwardly, and this is a construction that I prefer, but to which I do not desire tobe limited, because the cells may be arranged with both positive poles extended upwardly or both positive poles extended downwardly, and. in order that this feature of the construction may be understood T illustrate in Fig. 9 a modified arrangement of the conductor features which permit the positive poles of both battery cells to be extended downwardly. The casing 20 and exterior covering therefor employed in the construction shown in F 9 are identical with the like features hereinbetore described in connection with the construction shown in Figs. 1 to 7 inclusive and therefore the details as to these features will not be specifically entered into. lln Fig. 9 the battery cells 60, 61 correspond with the battery cells 36, 37 hereinbefore referred to, but are turned so thattheir positive poles extend downwardly, as shown in Fig. 9, and in the construction shown. in Fig. 9 T employ a wooden bloclr. 62 carrying a threaded sleeve 6 lens ring 6?, lens 66 and electric lamp and redoctor, all as illustrated in Fig. 3, and therefore not requiring specific description The construction shown in 9 is a modification in respect to the conductors for completing the circuit, and, otherwise said con struction corresponds with the structure shown in Figs, 1 to '7 inclusive At the back or the bloclr 62 is a vertical conductor strip 67 which has an inwardly bent portion corresponding with that numbered 414;

in 8 which enters the block andserves as a contact for the end terminal. of the lamp, and the said strip 67 has a lower extension 88 which extends below the block till 62 and is secured by arivet or the like 69 at its outer end in. positionto beengaged by the positive pole oi the battery The bloclr 82 has secured to its hash addr tional conducting strip 78 which extends the height of the block and has a laterally sittending upper end section Y1 secured on the too of the block 62 and at its or the base thereoi and its other portion extended downw oily, as at 7 along-the side of and eng rig the nine of the battery cell (all, Aboveithe cell 60 provide spring 7f? which serves" to maintain. said cell in firm position in engagement with the conductor 2; and above tne cell trill-provide a similar spring which pressingagainst the negative pole oi the battery 61 main tains the, positive pole thereof in electrical Extending verti arsen connection with the conductor 68. The

spring 7 8 is, also, by means of an eyelet 7 9', placed in electrical connection with the housing 80, which contains the switch slide 81, and said slide 81 is adapted'to be moved into engagement with an eyelet 82 concealed within the housing 80 whenever it is desired to complete the circuit and light the lamp. The eyelet 82 is in electrical connection with a spring 83 which presses upon the conductor 71 and thus is in electrical connection through the strip 7 0 and section 72 extending therefrom withthe positive pole of the battery 60. The lamp is in connection, through the strip 67 and extension 68, with the positive pole of the battery 61, and as aforesaid the'negative pole of the battery 61 is in electrical connection with the honsing 80 and switch 81. The strip 67 extends from one terminal of the lamp, and the strip 7% represented by the parts 75, 76 is in electrical connection with the other terminal of the lamp and also with the nine of the battery 60. The circuit is made or broken at the switch 81 in a manner which will be well understood from the description already presented. The construction shown in Fig. 9 embodies a rearrangement of the circuit conductors permitting the cells 60, 61 to beemployed in what may be said to be inverted position or with the positive poles extended downwardly and the circuit is indicated diagrammatically in Fig. 17.

Tn Fig. 10 I illustrate another modification of my flash light, and in this modification the changes from the constructionv shown-in the previously described figures of the drawings reside largely in the circuit connections permitting in this instance the positive holes of the two battery cells 90, 91 tov extend upwardly; The exterior casing shown in Fig. 10 is substanti ally the sameas' the exterior casing shown in theother figures of the drawings, and Fig. 10 being a modification T number the wooden block placed vtherein as 92, and this'block as in Figs. 7

and 9 carries the threaded sleeve 93 for the lens .94.- and lens ringf95. The cells 90, 91 are mounted upon conducting springs 96, 97, re-

lspectively, and the conducting spring 96 is seated upon a conductor strip 98 which ex tends inwardly along the bottom of the casing and then upwardly as indicated by the dotted'hnes 99, and-then inwardly, aS at 100,

to the metal" sleeve or the base thereof 93,

whereby the negative pole of the battery cell 96 becomes Placed-ineleotricalconnection with the side terminal of the lamp. The spring 9? is seated upon aconductor strip 101 which extends inwardly below the block 92 and then upwardly, as indicated by the dotted lines 102 along the side of the groove in the baclr of the block 92, said groove corresponding with the groove t2; shown in Fig. 5. The upper end of the vertical member' 'of the conducting strip 101 is bent laterally, as at 103, and secured to the top of the block 92. The positive pole of the battery cell 90 is electrically connected by a strip 104 with the upper laterally bent end 103 of the conductor 101, said strip 104'being secured by rivets 105 and 10 6 ;to the lower surface-of the top of theexterior main casing 20. The positive pole of the battery cell 91 is in electrical connection through a rivet or eyelet 107 with the switch housing 108, said rivet or eyelet 107 being utilized to secure one end of said housing on the top of the casing 20. The inner terminal of the lamp is in electrical connection with a vertical strip 109 which extendsupwardly througlrthe groove at the back of the block 92 and is bent over, as at 110, on the top of said block and secured thereto. A concealed eyelet 111 engages the upper'end of the strip 109and is exposed wit 1n the housing 108 and within said housing is the switch slide 112 which may be moved into engagement with the rivet or eyelet 111 and thereby complete the circuit through the lamp and battery cells. Fig. 18 illustrates diagrammatically the circuits for the construction shown in Fig. 10, and since Fig. 10 only illustrates a modified arrangement of the conducting strips for the circuit, I do not deem it necessary to enter into further detailed descrip tion concerning the same.

In Figs. 11, 12 and 13 I illustrate a further modification of the invention wherein the interior shell may be of metal, if desired, instead of nonconducting material, and in this instance thebattery cells 113 and 114 should he covered with non-conducting material 115. The casing shown in Figs. 11, 12 and 13 contains the wooden block 116 carrying the metallic sleeve 11?, reflector118, lens 119 and lens-ring 120, all as described with respect to the block shown in Figs. 3 to 7 in- I trated there will be provided all of the conclusive, and in the back of the block 116 there is a vertical conducting strip 121 which is bent inwardly, as shown in Figs. 12 and 13, to form a spring contact for the end terminal of the lamp, the other terminal of the lamp being in electrical engagement with the reflector. In the construction shown in Figs. 11, 12 and 13, the negative pole of the battery 113 rests upon a conducting strip 122 which extends inwardly and is connected with the vertical conductor 121, therebyplacing the negative pole of the battery 113 in electrical connection with the end terminal of the lamp. The negative pole of the battery 114 is in engagement with a conductor 123 whose inner end is in electrical connection with an eyelet or rivet 124 convealed within the housing 125. The positive pole of the battery 113 is in electrical connection with a conductor 126, which is secured to the housing 125 by an eyelet or rivet 127, andsaid positive pole of the battery 113 I is therefore in electrical connection with the housing 125 and switch 128 therein. The positive pole of the battery 114 is seated on a contact spring 129 which extends inwardly below "the block 116 and then vertically, as at 130, into electrical connection with the threaded sleeve 117 carried by said block. When the switch slide 128 is moved into an gagement with the eyelet 124 of the conductor 123 it establishes the circuit through the lamp and the lamp will become lighted, and when said switch slide 128 is moved from engagement with the eyelet 124, the circuit will be broken and the light will be extinguished. Fig. 16 illustrates diagrammatically the circuits for the construction shown in Figs. 11, 12 and 13, and since the construction shown in Figs. 11, 12 and 13 only diiiers from the construction shown in Figs. 1 to 8 inclusive in details of the casing construction, it is thought that only brief further detailed explanation of the construction shown in Figs. 11, 12 and 13 will be required. It is to be understood, however, that the cells 113 and 114 are insulated from the general casing, said casing being of metal, and that the upper and lower ends on top and bottom oi the casing must either be of insulating material or contain 'fiberlinings.

In the construction shown in the drawings, the flat back and front and rounded ends of a casing part 131 are formed in one piece, and a metallic bottom 132 is also formed in one piece with the casing part 131. The bottom 132 is provided with an insulating lining 133, and the upper end 134 of the casing is formed of insulating material and is arranged to be opened by means of a hinge 135 appearing in Fig. 12. Obviously the casing may be provided with an outer covering of leather or other suitable material if desired.

In all of the formsof the invention illusveniences hereinbefore described with rebeen deemed necessary to illustrate the exterior covering or wrapping, loops and other features in common for the constructions shown in Figs. 9 to 13 inclusive, since they will be the same as for the constructions presented in Figs. 1 to 5 inclusive. In each of the constructions shown is presented the oval casing containing the wooden block parallel battery cells and other features common to the construction shown in Figs. 3 to 7 inclusive. I present Figs. 9 to.-13 inclusive so as to indicate that my invention is not limited to all of the details of arrangeinents of conductors and other parts specifically described with respect to Figs. 1 to 8 inclusive. I

My invention is not therefore limited to details of arrangement for the circuits, nor

to other details of form or construction otherwise than the appended claims may re nire.
